1'0 (all whom it may concern/.-

Be it known that I, IRAWV. MOORE, a eitizen of the United States, residing at New York city, in the county and State of New York, have invented new and useful Improvements in Padlocks, of which the following is a specification.

My invention consists of a novel contrivance for the construction of padlocks in much sim 1O pler form and cheaper than other 'padlocks now made, as follows: I use a case consisting of two cup-shaped parts, each preferably having a rigid arm forming part of the hasp, but the hasp may be wholly on one part, pivoting 15 said parts together, so that they will turn on the pivot to open and close the hasp, and con struct said cup-shaped parts with sockets for receiving locking studs, and with ways for the studs to slide on when the lock opens and 7 2O closes; in an arrangement whereby said sockets and ways may be formed in the parts of the lock-case by the casting of the same; and lluse therewith a locking device of simple and cheap construction, and thusproduce a lock of very cheap cost, but of substantial and durable construction, all as hereinafter fully described. reference being made to the accompanying drawings, in which Figures 1 and 2 are side elevations of the two parts of the lock-case, respectively,showing the interiors of the same. Fig. 3 is a sec tional elevation of the lock on the line .90 m of Fig. i. Fig. 4 is a transverse sectional elevation of the look when locked. Fig. 5 is a see tional elevation on line 00 at of Fig. 4, showing modifications. Figs. 6 and 7 are details.

I use two cups, a b, for the case, each having an arm, 0, formed rigidly on the rim,suitably for constituting the hasp of the lock, by

0 closing together at the ends to secure the lock to the hasp, staple, or other thing to be looked, and swinging apart to release the same, said cups being placed edge to edge and fastened by a pivot-stud, (l, that may be fitted at the center of the cups, or in any position suitable for allowing the hasp to be opened and closed, for example, as represented in Fig. 5. Inside of each of these cups I form two or more sockets, c, for locking-studs f, making them in metal I rising up from the bottom of the cups o flush with the edges h of the rims of the cups, which bear against each other and form the surfaces whcreon the cups turn in opening and closing, and along the courses the sockets of the respective parts of the case swing to and from each other in the opening and closing of the look. I arrange the ways 2' flush with the surfaces of the 11101111 in which the sockets are formed for the locking-studsfto ride on to be kept in position while the lock is open for dropping into the sockets and locking the lock when it is closed, said sockets being arranged in the two parts of ,the case, so that the sockets of one part of the'case coincide with the sockets of the other part when the lock is closed to allow the locking-studs of one part of the'case to be thrust forward partly into the sockets of the other parts of the ease and across the joints between the two parts by the springs j behind the studs in the sockets of one of the parts of the case. These lockingstuds are of different lengths, to be used with a key, k, having bits Z of different lengths, and specially fitted to the studs for setting the studs, so that the joints between all the studs of the two parts of the case will coincide with the joint between the two parts of the look, as represented in Fig. 7, when the key is thrust into the holesm a predetermined distance controlled by the stops at. In one of the parts of the lock-ease I provide for forming a stop, 0,

in the casting of the same, that shall project up a little above the surface of the rim, so that one of the studways i of the other part of the case will come in contact with it when the lock has opened as much as is required, and prevent the further opening, and thereby prevent the escape of the studs f from the end of the ways i, employed to hold-them in their sockets. The cups a b may of course be cast 0 full, so that the whole inner surface will be flush with the edges of the rims h, also with the metal g for the sockets and the slidleways i for the studs, in which case the slideways z and the socket-metal 9 would not be distinct- 5 ively defined as to the rest of the metal filling the cups, but would nevertheless constitute distinctive features of the lock all the same; but such construction would entail considerable unnecessary waste of metal and add considerable unnecessary weight to the look.

In Fig. 5 I have represented the pivot d as located near the rims of the cups, with the socketsand stud-ways more in the central portion of the case, and I have also represented the hasp as formed wholly on one parti be made of the look, if desired.

Locks made of two cup-shaped parts, each having an arm to form the hasp, and being pivoted together and provided with looking devices, have been made before, and the looking contrivance, consisting of aseries of studs, f, and springs j, arranged in sockets e and operated by a key, having bits adapted to the making the locking-studs, springs, and the key, all of which are very simple.

What I claim, and desire to secure by Letters Patent, is

Y 1. A padlock consisting, essentially, of two parts, a b, having a rigid hasp, and being pivoted together for opening and closing the hasp, its-described, the said parts each formed with sockets e, and also with guideways i for locking-studsf, in combination with the connecting-pivot d, said sockets and studs being located in interior portions, of said parts flush with the bearing-edges'h of the rims, as set forth.

2. A padlock consisting, essentially, of two parts, a I), having a rigid hasp, and being pivoted together for opening and closing, as described, the said parts each formed with sockets e and guideways-z' for locking-studs], and one of said parts having astop,-o, sub-' stantially as specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
